| comments | The enzymes in this entry are parts of genome polyprotein from foot-and-mouth disease virus, which is composed of 4 coat proteins, 3 core proteins, 2 proteases (leader protease, picornain 3C), genome-linked proteins, 3D polymerase. The tertiary structures for the 4 coat proteins (PDB; 1zba, 1zbe) and a protease (E.C. 3.4.22.28, PDB;2bhg) have been solved to date. The enzyme (picornain 3C; EC 3.4.22.28) cleaves GLN/GLU-|-GLY/SER/THR bonds in its polyprotein. The catalytic domain strucutre for the peptidase has been solved so far. This protease belongs to the peptidase family-C3, to which picornain 3C from other picornaviruses (M00209, M00217) and picornain 2A (EC 3.4.22.29;M00217) belong. The catalytic mechanism of this enzyme seems to be similar to that of trypsin (D00197 in EzCatDB), which is its homologous enzyme, although its catalytic site is composed of Cys/His/Asp and mainchain amide groups.
